JOHN E. WARD, OF NEW YORK, N. Y., ASSIGNOR TO STANDARD HEAT AND VENTILATION COMPANY, A CORPORATION OF NEW YORK.

PIPE-COUPLING.

i ,oaaeeo T0 all 'to/0m it may concern Be it known that I, JOHN E. WARD, a citizen of the United States, and a resident ot the borough of Manhattan of the city of New York, in the county andState of New York, have inventedl certain new andy usc ful Improvements in Pipe-Couplings, of which the following is a specification.

The invention relates to improvements in pipe couplings and particularly to couplings adapted for use in steam heating systems tor railway cars. The pipe couplings to which this invention is particularly directed are preferably utilized with flexible rubber pipes to which they are connected. Each of the pipe couplings comprises a coupling head or body portion anda nipple portion which engages the end ot the flexible pipe. rlhe body and nipple portions have a ball and socket connection'between them to permit the body portion of the coupling;f to move relative to the nipple portion without causing an undue bending or kinking ot' the flexible pipe.

s showing a specific embodiment 0f the invention reference is made to the drawings forming a part of the specification in wl1ich Figure l is a vertical longitudinal sectional view of the pipe coupling shown in Figi. Q. liig. 2 is a plan View of that form ot pipe coupling which is shown in section in Fig. 1. Fig. illustrates a different manner ot' holding the nipple portion or member in place in the body member from thal illustrated in Figs. l and 2.

ln the construction shown in Figs. 1 and Q the body or coupling head is designated by the reference character l` and the nipple portion bythe reference cl'laracter 2. The nipple portion 2 conipriscs at one end a part fl which is particularly designed and adapted to be connected to the end of a flexible rubber pipe of a steam heating system tor railwav cars and at the other end the spherical ball portion l constituting a part of a flexible universal connection between the body and nipple The body portion comprises the wedge portion 5 and the seat or washer G each of which coperate with the proper members of a companion'eoupling Specication of Letters Patent.

is provided with a hollow spherical portion 7 in which the spherical ball portion 'l of the nipple is seated and securely held. The seat 6 extends a sullicient length and is shaped to tightly tit with the spherical portion 4 of the nipple whereby when the coupling head is wedged in operative posi, tion with a companion coupling head a tight joint may be 'forn'ied between said seat G and the nipple 2. The body l is preferably formed of some metal that is capable ot being wrought whereby the holding lips 8 can be bent from the dotted position 9 to the position shown in 'full lines and thus retain the spherical portion of the nipple in the socket of the body portion.

In the form shown in Fig. 3 it will be observed that there is comprised the body portion l and the nipple portion 2, the former ot' which is provided with a fi emi-spherical seat to receive the spherical portion on the latter. These parts are tightly held in place by means of the nut A10 on the body portion. It will be observed that in this form the seat or washer (3 does not extend to and engage the ball end ot the nipple, but manifestly the scat could be extended as in Figs. 1 and 2 to engage the ball portion of the nipple. It will furthermore be noted that the body shown in Fig. 3 need not be of `a material capable of beingr wrought as the ball end of the nipple can be retained in place by the nut 10. The construction shown in Figs. l and 2 can readily be modified so as to employ the nut l0 shown in Fig. 3 as a means for retaining the nipple in place in the body member if desired.

It will .be apparent in each ot the forms above described that the ball and socket connection between the nipple portion and the body portion ot the couplingr constitutes a flexible universal connection between said portions.

It is obvious that various forms and modi fications may be made without departing from the spirit and scope of the invention.
